Small business optimism continues to climb in the third quarter as business owners said they are the most optimistic in more than a decade, according to findings from the Wells Fargo-Gallup Small Business Index. In the quarterly survey, which measures the optimism of small business owners, the overall Index score jumped to 106 in July – an 11-point increase from 95 in April and the highest since 113 in April 2007. The increase in optimism was driven by several factors. One factor is healthy revenues. For the second quarter in a row, almost half said their business’s revenue increased over the past 12 months, up from 41 percent a year ago.
